Combustion runs at 700 °C in a horizontal laboratory furnace were carried out on two different electric wires (PVC and halogen-free wire). Tests were performed in the presence and in the absence of the metal conductor of the wires. The analyses of the polycyclic aromatic hydrocarbons (PAHs), chlorobenzenes (CBzs), chlorophenols (CPhs), mono- to octa-chlorodibenzo-p-dioxin and dibenzofurans (PCDD/Fs), and dioxin-like PCBs are shown. Regarding semivolatile compounds, PAHs production decreases in the presence of metal, while a higher amount of chlorinated compounds are emitted. Respect to the PCDD/Fs, the PVC wire in the presence of metal presents the highest emission, with a much more emission of furans than dioxins. The maximum emission is with 2 or 3 chlorine atom PCDD/Fs. PCBs emission correlates with PCDD/F production and represents 3-4% of total toxicity, determined by using WHO2005 factors.
在水平实验室炉中以 700°C 的温度进行了两种不同电线（聚氯乙烯和无卤电线）的燃烧实验。在存在和不存在电线金属导体的情况下进行了测试。分析了多环芳烃（PAHs）、氯苯（CBzs）、氯苯酚（CPhs）、一至八氯二苯并对二恶英和二苯并呋喃（PCDD/Fs）以及类似二恶英的多氯联苯（PCBs）。对于半挥发性化合物，金属的存在会降低 PAHs 的生成，而会排放出更多的氯化化合物。对于 PCDD/Fs，存在金属的聚氯乙烯电线的排放量最高，呋喃的排放量远高于二恶英。具有 2 或 3 个氯原子的 PCDD/Fs 的排放量最大。PCBs 的排放量与 PCDD/F 的生成量相关，占使用世界卫生组织 2005 年因素确定的总毒性的 3-4%。
